.xls is proprietary and contains more than just the data, not sure if your functions are accurate, but they appear to match what I have seen before

excel can read/write .csv comma separated values
php can read/write .csv comma separated values
which is great if the data is all you need, not sure if equations transfer

a bunch of tutorials on creating writing .xls with phphttp://www.google.com/search?php .xls tutorial have no idea how myself

(Good Luck)
